Contact Ellery ADU Studio Rancho Cucamonga - Free ADU Estimate in Rancho Cucamonga
Call (909) 506-1121 to schedule your free ADU estimate in Rancho Cucamonga. When you reach us, you’ll talk to a live coordinator who connects you with Nadia Ellery’s local team. There’s no hard sell, no deposit to book the assessment, and we can usually get to your property within a few days. We’ll walk your lot, talk through what you want the unit for - rental income, family, office - and explain what Rancho Cucamonga’s ADU ordinance actually allows on your specific parcel.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up during business hours and takes down your address, your goals for the ADU, and any timeline you’re working toward. You’ll get a sense right away whether we’re the right fit, and we’ll be straight with you if your project needs something outside our scope.
Step 2: We schedule a site assessment. Nadia Ellery or a senior member of our Rancho Cucamonga team visits your property, measures setbacks, checks utility access, and identifies any oak tree protection zones or slope constraints that Rancho Cucamonga’s planning department will flag. This visit is free and carries no obligation.
Step 3: You receive a written, line-item estimate. Within 48 hours of the visit, we deliver a fixed-price proposal: design, permit set, site work, and construction. Clause 1 of The Haven Standard - Have it in writing - means the price you see is the price you pay. No change orders unless you change the scope.
Step 4: We build to the drawings. Once you sign, we handle the Rancho Cucamonga permit submission, coordinate inspections, and execute the build. Every phase is photographed and logged. When we leave, you get a documented record of what was actually built, under warranty.
Why Rancho Cucamonga Homeowners Call Us First
- We know the local timeline. Rancho Cucamonga’s planning department processes ADU permits on a predictable rhythm, and we’ve learned where the logjams form. That local knowledge gets your project into the queue faster than a studio learning this market from scratch.
- Every pro on your job is required to hold the license and insurance California requires. We verify coverage before anyone sets foot on your property, and license numbers are listed on your contract. You’re not guessing who’s actually doing the work.
- Transparent pricing with no hidden fees. Your written estimate breaks out design, permitting, site prep, construction, and finish materials. If Rancho Cucamonga requires a soils report or fire sprinkler upgrade based on your lot, we flag it in the initial quote - not after demolition starts.
- The Haven Standard workmanship guarantee. Every ADU we build in Rancho Cucamonga carries a written warranty backed by our parent brand’s 11-year track record. If something fails because of how we built it, we fix it. Clause 5 - No surprises - applies to the warranty too.

Frequently Asked Questions - Booking & Estimates
Yes. The site assessment and written estimate cost nothing and carry no obligation. We believe you should know the real price before you decide anything. Call (909) 506-1121 to schedule yours.
We typically schedule site assessments within 3 to 5 business days of your call, depending on Nadia Ellery’s current project load. During slower periods, we’ve gotten out next-day. We’ll give you an honest window when you call - no phantom urgency.
No. Our standard hours are 7:00 AM to 7:30 PM, seven days a week, and assessments during those hours are priced the same. We don’t do after-hours emergency calls - ADUs are planned construction, not burst pipes - so we don’t pretend otherwise.
Your property address, a rough idea of the ADU size or type you’re considering (detached, garage conversion, junior ADU), and any hard deadline you’re facing. If you have a recent survey or know your lot size, that’s helpful but not required. We’ll pull the zoning basics from Rancho Cucamonga’s GIS before we arrive.
We accept check, ACH transfer, and major credit cards. The payment schedule is spelled out in your written contract - typically a deposit at permit approval, progress payments at defined construction milestones, and final payment at substantial completion. No cash-only demands, no surprise payment requests.
